Descripción
We studied the Fe and Mo valence states in Sr2FeMoO6 using X-ray absorption spectroscopy. The exper- imental results were analyzed using atomic multiplet plus crystal field calculations. The analysis indi- cates that the Fe ions present a fairly ionic Fe3+ (3d5) valence, and that the Mo ions are in a strongly covalent Mo5+ (4d1) state. The presence of Fe ions in a 2+ valence state can be excluded from the Fe-L2,3 spectrum. These results can be understood taking into account the relative energy of the d-levels, the relative strength of the M d?O p mixing, and the exchange stabilization of the Fe3+ ion.
